What will the request form ask about the boiler?
The same three questions as for a furnace; choose "Boiler (radiators or floor)" for the first. The most useful photo is the label inside the boiler's door or cover, and any code on its display.
| Question | The choices |
|---|---|
| What heats the home? | Furnace · Boiler (radiators or floor) · Not sure |
| How old is it? | Under 5 years · 5 to 10 years · Over 10 years · Not sure |
| What is it doing? | Not coming on · Some rooms cold · Blinking light or code · Noisy |
Photos that help. The most useful are the label inside the furnace or boiler door, and any blinking light or code.
How does a hot water heating loop work?
The boiler heats water, a circulator pump moves it up to the radiators or the floor and back, and an expansion tank, an air separator and a relief line keep the loop at a safe pressure. Rooms cold at the far end of the loop, banging or gurgling, or a pressure reading that keeps dropping all point to different parts, so say which you see.
